Instructions
Preheat the oven to 400°F and position the rack in the center. Line a baking sheet with parchment paper and pat the mahi mahi fillets dry with paper towels.
Place the fillets on the baking sheet. Lightly brush with olive oil, sprinkle with Old Bay seasoning, and top with small cubes of butter.
Bake for about 11 minutes, starting to check at 10 minutes and adjusting for fillet thickness. The fish should reach an internal temperature of 145°F in the thickest part.
Let rest for 2 minutes, then spoon the melted butter over the fish. Garnish with parsley and optional lemon zest, and serve with lemon wedges.
Notes
Cooking time: My fillets took 11 minutes at 400°F. Start checking at 10 minutes and adjust for thickness.Butter is optional: Skip the butter for a dairy-free option or to cut calories, but keep the olive oil. The melted butter creates a sauce to spoon over the fish before serving.Seasoning: Old Bay contains salt, so taste before adding more. For a spicier variation, use homemade blackened seasoning.Frozen fish: Thaw according to package instructions and pat dry before seasoning.Storage and reheating: Refrigerate leftovers in an airtight container for up to 3 days. Reheat gently in the oven, microwave, or a skillet with a little olive oil.
